Detection and Resolution of Data Confliction in the Integration of Heterogeneous Information Sources

As the development of computer technology,the information integration begins to be the key part of the enterprise information system development.The key problem of the heterogeneous database information integration is the detection and resolution of data confliction.According to the integrating processing,a classifying layer model of data confliction and the integrative resolution of those kinds of confliction were proposed. Due to the attribute matching in heterogeneous database semantic integration,attribute-space-match algorithm is presented according to the idea of establishing attribute space.
